Linguistic syntax is especially marked by its structural richness which becomes apparent in its multi layered organization as well as in the strong relationship between syntax and meaning. That is that there are special linguistic syntactic principles which define how the language is formed out of different subunits, such as words out of [[morphemes]], phrases out of words and sentences out of phrases. The fact that a change in the order of subunits especially in the order of phrases in a sentence can add to a change of meaning, appears to set human language apart from nonhuman animal [[communication systems]]. The sentence “The child with the red shirt hit the man.” has a completely different meaning from the sentence “The man with the red shirt hit the child.” Furthermore, linguistic syntax is featured by the fact that a word can take on abstract [[grammatical functions]] which are less defined through properties of the word itself but through the context and structural relations. This is for example that every [[noun]] can be used as a [[subject (grammar)|subject]], [[object (grammar)|object]] or [[indirect object]], but without a sentence as the normal context of a word, no statement about its [[grammatical function]] can be made. At last, linguistic syntax is marked by abstractness. This means that only conventional structural relations and not psychoacoustic relationships are the basis for the linguistic syntax.
